Manufactured from submicron solid carbide, it delivers superior rigidity and wear resistance compared to standard carbide grades. The bar features a bright finish, right-hand cutting direction, and a corner radius range of 0.0050 to 0.0080 inches, making it well suited for controlled corner blending and precision bore sizing. A 5\/16-inch shank diameter and 2.5-inch overall length give machinists a compact, stiff tool body that minimizes deflection in tight bore entries starting at 0.29 inches.\u003c\/p\u003e\u003cp\u003eThis boring bar is appropriate for light to medium-duty internal turning operations where close-tolerance bore diameters and consistent corner geometry are required. Typical applications include bore finishing in ferrous and non-ferrous workpieces on production and job-shop turning equipment. The right-hand cutting orientation suits standard spindle rotation in conventional CNC lathe setups. Maximum bore depth reaches 1.35 inches, covering a wide range of short-to-medium depth internal features common in component machining.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for extended tool life and reduced deflection\u003c\/li\u003e\n\u003cli\u003eCorner radius range of 0.0050 to 0.0080 inches for precise edge blending\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.29 inches suits tight internal features\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 1.35 inches accommodates a broad range of workpiece geometries\u003c\/li\u003e\n\u003cli\u003eBright finish coating resists built-up edge in light cutting conditions\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting direction for standard CNC lathe spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style boring bar for use in standard boring bar holders accepting a 5\/16-inch round shank on CNC lathes and manual turning centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer's tooling setup procedures. Ensure the machine spindle is fully stopped and the control is in E-stop or lockout before mounting or removing tooling. Secure the shank in a compatible boring bar holder to the holder manufacturer's specified clamping torque using calibrated tooling. Verify runout and overhang before commencing cuts to minimize deflection at the listed minimum bore diameter.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoring Bar Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.29 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1.35 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3125 inches (5\/16 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0050 to 0.0080 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Bright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.125 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: B2901350R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51740152168754,"sku":"B2901350R","price":60.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/88be5f7293aa72f4816b4d0325453b8e.jpg?v=1788822955","url":"https:\/\/voomisupply.com\/products\/accupro-b2901350r-corner-radius-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
